Rande Bly of Birmingham, AL sends this along:

The Tyndall effect, reflected) by particles in a colloid solution. This makes a beam of light visible by a color change as it passes through that solution. Mousselene will come in colloidal glass types with the effect amplified by the addition of opalescent glass. Cerise Ruby is a colloidal glass.

When Opalescent glass is viewed from a right angle to the light sources the glass appears translucent to opaque and the color blue. If you view the glass at no angle to the light source the glass appears to be more transparent and orange/amber in color. When mixed with Carder’s Cerise Ruby, Alabaster based Jades, Ivory, or Cardinal Red you get a very interesting and beautiful result. This is why Henna Alabaster will throw hints of a slight gray or blue. It is also the reason the Cerise Ruby Mousselene pieces are noticeably more orange than your typical ones.

Opalescent glass is dichromatic depending on the angle of the light source versus the viewing angle. This effect can be most amplified in a Ripple vertical ribbed, or a melon ribbed pattern. We see same color change illusion in theater drapery. He carefully incorporated all these factors into his Mousselene glass to achieve a more radically varying transparency and color change between ribs. I can see why Oriental Jade and Oriental Poppy have such a strong striped appearance. His Mousselene pieces have an enhanced striped appearance also.

We talk about Carder being a genius but we need to stop for a moment and realize how true that was. Nothing was by accident with him, but every move he made was carefully calculated through chemistry, science, and design. He was self taught in a variety of advanced fields. What else made him the greatest in the world?
